![]() We’ll use the simplest method to install, which is the postrgres repo ]# yum list postgres* If you are looking trying to install PostgreSQL 9 on cPanel, please see my post here. We will also creating symlinks (if needed) from the new PostgreSQL 9 file locations to the previous PostgreSQL 8 file locations. With the release of PostgreSQL 9, the directory structure of PostgreSQL has changed. ![]() I am using CentOS 6, but the same procedure works for CentOS 5.įinally, if you are using Webmin, we will also show how to configure Webmin to manage PostgreSQL 9. Optionally, we’ll also see how to install PostGIS.Īs the directory structure of PostgreSQL has changed with the release of PostgreSQL 9, we will also look a look at how we can create symlinks to make life easier when installing software or modules that still expect the old directory structure.įinally, for Webmin users, we will see how to configuring Webmin to manage PostgreSQL 9. ![]() The same procedure can be used to install PostgreSQL 9 on Red Hat and Fedora using the appropriate rpm. We will install PostgreSQL 9 using the PostgreSQL repository and yum. 7.This post will cover installing and basic configuration of PostgreSQL 9.x on CentOS. Here, in short, we restored all the tables of the baeldung database using the psql command. Now let's check out the command to restore the database: $ cat dump.sql | docker exec -i postgresql psql -U baeldung We provided the username of the DB server to access the privileges. It's a standard PostgreSQL tool for backing up the database. In the above command, we used pg_dumpall to backup the baeldung database. Now let's look into the command to back up a database for a Docker container: $ docker exec -t postgresql pg_dumpall -c -U baeldung > dump.sql So far, we've created a database and a table. "baedlungauthor_pkey" PRIMARY KEY, btree (author_id) Now we'll use the below command to get the schema detail of table baeldungauthor: psql -U baeldung -d baeldung -c "\d baedlungauthor"Ĭolumn | Type | Collation | Nullable | Default Public | baedlungauthor | table | baeldung Let's list out the created table in the database: psql -U baeldung -d baeldung -c "\d" The command to create a table is as follows: CREATE TABLE baeldungauthor ( $ createdb -h localhost -p 5432 -U baeldung baeldung In order to access the database, we have to set up a connection to the Postgres server using pgAdmin. We can easily access PostgreSQL databases using the pgAdmin GUI. In the above command, we provided the PGADMIN_DEFAULT_EMAIL and PGADMIN_DEFAULT_PASSWORD as an environment variable to the pgadmin-baeldung container: To demonstrate, let's run the container using the below command: $ docker run -name pgadmin-baeldung -p 5051:80 -e " " -e "PGADMIN_DEFAULT_PASSWORD=baeldung" -d dpage/pgadmin4 Status: Downloaded newer image for dpage/pgadmin4:latest To do this, we need to pull the pgAdmin image using the following command: $ docker pull dpage/pgadmin4:latestĭigest: sha256:f820e5579857a7210599f998c818777a2f6f39172b50fbeb2faaa1a70413e9ac To perform all the queries from the UI, we can use the pgAdmin. pgAdmin can be used to run SQL queries on PostgreSQL databases. Now we'll install pgAdmin, a web-based user interface tool used to manage PostgreSQL databases and services. So far, the PostgreSQL server is active and running on the 5432 port. To back up the data, we also mounted the /var/lib/postgresql/data directory to the /data directory of the host machine of the postgres container. We exposed the 5432 port on the host using the “-p 5432:5432” in the docker run command. By default, the PostgreSQL database runs on the 5432 port. The above command uses environment variables POSTGRES_USER and POSTGRES_PASSWORD to set the username and password for the PostgreSQL database. Now we'll run the Docker container using the postgres:latest image with the below command: $ docker run -itd -e POSTGRES_USER=baeldung -e POSTGRES_PASSWORD=baeldung -p 5432:5432 -v /data:/var/lib/postgresql/data -name postgresql postgresĥaeda2b20a708296d22db4451d0ca57e8d23acbfe337be0dc9b526a33b302cf5 Status: Downloaded newer image for postgres:14.2 We can also pull a particular version of the postgres image using the below command: $ docker pull postgres:14.2ĭigest: sha256:e3d8179786b8f16d066b313f381484a92efb175d1ce8355dc180fee1d5fa70ec In the above command, we pulled the postgres latest stable image. Status: Downloaded newer image for postgres:latest To run a PostgreSQL using Docker, we first need to pull the postgres public image available on Docker Hub: $ docker pull postgresĭigest: sha256:ab0be6280ada8549f45e6662ab4f00b7f601886fcd55c5976565d4636d87c8b2
